Steel shelf



R. J. KORESKA Jan. 4, 1966 STEEL SHELF Filed Oct. 1, 1962 layer lies'ina protected position in under the shelf and the freely exposed portionof the plastic layer is not exposed to damage through impact.

The invention relates furthermore to a holder for the ribbons withinformation. This holder is characterized in that it consists in asubstantially U-formed rail, where the free ends of the arms haveportions bent toward each other and where a yieldable list is placed inthe rail, said list bearing yieldably to one side against the backportion of the U-formed rail and to the other side against the bentportions of the arms.

In the drawing are shown four embodiments of a steel shelf according tothe invention, wherein FIG. 1 shows a cross section of a steel shelf ina first embodiment,

FIG. 2 a cross section in the front edge portions of a steel shelf in asecond embodiment,

FIG. 3 a cross section in the front edge portions of a steel shelf of athird embodiment and FIG. 4 a cross section in both lateral sections ofa steel shelf in a fourth embodiment.

In the drawings a sheet steel part comprises a rectangular, plane mainportion 1 with a relatively slight thickness, e.g. 0.7 mm., along theforward edge of the main portion 1 an approximately 180 curvature 2,continued by a rearwardly extending first strip-shaped portion 3substantially parallel to the portion 1, and in continuation of theportion 3 a Second stripshaped portion 4 extending approximately atright angles to the plane of the main portion; in connection of thisportion 4 there is a forwardly directed third strip-shaped portion 5.The rear edge portion of the sheet steel part is bent upward to form avertical supporting wall 6. On the underside of main portion 1, in theproximity of the rear edge, is fastened a U-shaped rail 7, the openingof which forms a groove directed toward the front edge of the shelf. Thecurved main portion 2 and the strip-shaped portion 3 together form acorresponding groove at the front edge of the shelf.

' The ends of the main portion 1 may be bent downward (not shown) sothat the shelfs ends can be hooked into bearing rails in a book-case.

The innermost portion of the strip-shaped portion 5 may be bent slightlyupward so that the groove formed by the strip-shaped portions 3, 4 and 5can hold a ribbon with information which can be set in from the end or,if it consists of elastic material, can be edged into place.

In the grooves at the front end and the rear edges and projectingdownward under the shelf may be placed guide portions of a book-endhaving a downwardly projecting looped spring member which connects theguiding portrons and press them yieldingly into said grooves undersidethe main portions.

On the front side of the strip-shaped portion 4 in the embodiment shownin FIG. 1 is fastened by spot welding a U-shaped rail with a backportion 8 and two arms 9 and 10 that are provided with edge portions 11and 12 directed toward each other. In said U-shaped rail is placed astrip of foam rubber 13 holding a plastic ribbon 14 pressed against theedge portions 11 and 12. The plastic ribbon may carry information on itsfront side. By pressing it inward the ribbon may be displaced along thefoam rubber strip. Several short plastic ribbons may be employed on oneshelf. The foam rubber strip 13 extends preferably along the wholelength of the shelf. The plastic ribbon 14 has preferably such a widththat when pressing at the top or the bottom it can be pulled out at theopposite edge. Insertion may be per formed in the same manner.

On the upper side of the main portion 1 there is glued a flexibleplastic material 15 which at its one edge abuts the upwardly extendingportion 6 while said material at the opposite edge is bent around thecurvature 2 and under the strip portion 3 onto which it is also glued.

In the embodiment shown in FIG. 2 the portions 3 and 5 are inclined sothat they provide an undercut groove. In this groove there is inserted awooden list 16 in the front side of which there is formed a groove 17for inserting rearwardly projecting fixing means of plastic letters. Thewooden list may be replaced by a plastic strip having informationthereon.

In the embodiment shown in FIG. 3 the strip-shaped portions 4 and 5 areomitted. On the underside of the main portion 1 there is secured, forinstance by spot welding, a horizontal strip-shaped portion 18 of asteel sheet profile rod which is formed with a curvature 19, ahorizontal arm 20 bearing against the upper side of the portion 3, avertically downwardly extending stripshaped portion 21 and a forwardlyextending, bent edge portion or strip-shaped portion 22. The profile rodis substantially heavier than the steel sheet from which the mainportion 1 is made.

The steel shelf shown in FIG. 4 consists of a steel sheet part formedwith a rectangular, plane main portion 23, at each longitudinal edge ofsaid main portion with an approximately 180 curvature 24 and 25respectively, and in continuation of this curvature a profile portionwith generally C-profile comprising a back portion 26 and 27 an uppercurved arm 28 and 29, and a lower curved arm 30 and 31, respectively.The outer portions of the arms converge greatly. In the undercut grooveformed by the profile portions 27, 29, 31 there is arranged a list 32consisting of foam nylon and shaped to fill the groove elastically sothat it presses against the back portion 27 and against the convergingouter end portions of the arms 29 and 31.

A strip 33 of sheet material, preferably an elastic material, isinserted in the groove in front of the list 32 so that the latter keepsthe longitudinal edges of the strip 33 pressed against the convergingend portion of the arms 29 and 31 so as to retain the strip 33 inposition.

Pressing inward on the strip 33 results in loosening the latter so thatit is easily displaced in the longitudinal direction of the groove. Ifthe strip 33 consists of elastic material it will be easily insertedinto the groove and removed therefrom without displacing itlongitudinally.

I claim:

'1. A steel shelf comprising, in combination, a planar sheet memberformed with a rectangular, plane main portion and a curved portion alongat least one longitudinal edge thereof and extending throughout an arcof at least approximately 180 degrees, said curved portion having at oneside a flushing transition to said main portion, a first strip-shapedportion in continuation of the other side of said curved portion andhaving a flushing transition to said curved portion and beingsubstantially parallel to the plane of said main portion, and a secondstrip-shaped portion in continuation of said first strip-shaped portionextending generally away from and approximately at right angles to theplane of said main portion and parallel to said one longitudinal edge.
